Vbit question about software depth

I’ve searched the forum but couldn’t find the answer I’m looking for. I guess I don’t understand what I’m suppose to set my 60 degree or 90 degree bit depth at. do I just accept the depth the software sets it for. If so, why does it give me a choice of depth. I know that the software will not let Vbit letters or images to run together. How do I set it?

You select depth in order to control max depth , then the bit will do several side steps to carve the total width needed. (when total width is greater than one pass and max depth)

I am not sure what you mean, but text overlaying an image for instance can be combined into one object. Select text and image and use the Combine function.
